目的:对不同产地楮实子及其伪品进行指纹图谱鉴定分析。方法:用近红外漫反射光谱技术及聚类分析方法对楮实子药材及其伪品进行分析。结果:不同产地楮实子之间指纹图谱存在一定差异,与伪品差异较大。结论:该方法可用于楮实子药材的指纹图谱鉴定,快速方便。不同产地楮实子之间的差异与药材性状有一定关联。
Objective: To identify and analyze fingerprints of Fructus Aurantii and its pseudo-products from different origins. Methods: Near-infrared diffuse reflectance spectroscopy and cluster analysis were used to analyze the medicinal materials and their counterfeits. RESULTS: There were some differences in the fingerprints between the pods of different producing areas and there were significant differences between the samples and the counterfeit products. Conclusion: This method can be used for identification of fingerprints of Fructus Aurantii, which is fast and convenient. The differences between the pods from different habitats are related to the traits of herbs.
